To all whom t may concern.'

Be it known that I, HARRY T. LIBBY, a citizen of the United States, residing at Kankakee, in the county of Kankakee and State of Illinois, have invented a certain new and useful Improvement in Hydraulic Conveyers, of which the following is a speci- ,catiou This invention relates to hydraulic conveyers of use wherever dirt or otherwaste material can be conveniently transported by the aid of water under pressure. The invention is specially applicable to use in connection with stone quarries, gravel pits and the like where piles or layers of dirt material, with or without the presence of rock in comparatively small sized pieces, has to be removed so that the workmen can get at the solid rock or other material which is to be quarried. ,Because of this use of the device, it is shown in the drawings as installed at the edge of a stone quarry; but this illustration of the invention is not intended to in any way limit its scope or usefulness. i

The object of the invention is to provide an apparatus which can be very easily and cheaply made, which is very eiicient in use, which is not readily liable to get out of order, which is adapted for ready transportation with very slight labor from one point to another for work and from ontl point to another in the work, the same being adapted to wash away the dirt or other material to be conveyed away, and to thence convey that material to a distant point where it is out of the way of the workmen who are to quarry or otherwise remove the material which is in the rst instance covered by the waste material. The inven- 4tion consists in means for carrying out the foregoing and other objects, which has in addition the special advantage of being able to transport the material to be carried from a lower to a higher level and tof do this efficiently and cheaply without the installation of expensive machinery. The invention further consists in many features and details of construction which will be hereafter more fully set forth in the specilication and. claims.

Referring to the drawings in which like numerals designate the same parts throughout the several views: 'Figure 1 is a side view largely in section of one edge of a stone quarry in which the mechanism of the quarry a ridge or pile 16 of dirt and rock composed of ordinary dirt and chunks of rock 18, usually placed there by steam shovel operations in the quarry. The work in hand is to remove the pile of dirt 16 and the layer of dirt 12 a substantial distance to the right of the figures here shown, so that workmen may remove the pieces of rock 18 and may quarry the solid rock 10, and tc do this with the simple apparatus, eicient in operation and satisfactory in use.

The particular embodiment of the invention shown in the drawings includes conventional form of washing nozzle mechanism 20, having a tiltable nozzle 22, adapted to direct a stream of water 24 in any desired direction for the purpose of driving dirt before it. This mechanism 20 is supplied with water under pressure through a system of piping 26-28 of any conventional form. In the particular case here illustrated, the water under pressure is delivered to pipe 28 from centrifugal pump 30, drive-n by any suitable means, as, for inst-ance, an electric motor 32` the pump drawing water into itself through a pipe 34, leading to any suitable source of supply, not shown.

Pipes 26 and 28 are joined together by a -Tf'junction 36, to whose branch 38 is attached a hose 40, leading to the side of pipe 26-28 and terminating in a nozzle 42 supported by a screen cap 44, having in it perforations of sufficient size so that water, dirt and rock particles of normal size, which it is desired to carry away` may pass through them. This cap 44 is suitably attached, for instance by screw threads 46 on the end of a` Waste material conveyer pipe 48 leading away to a distant point at the right ofthe figures shown tothe place of disposal of the material to be conveyed. While pipe 48 has been referred to as a Single pipe, there isy nothing in the invention 'to prevent its being a line of pipe of considerable length, made up of separate pieces of pipe. The discharge end 42a of nozzle 42 enters the left hand intake end of pipe 48 a suificient distance so that when water from pump 30 is forced through this nozzle 42 in a stream 50 inside of pipe 48, the device acts as an injector sucking any and all materials which will pass through the screen 44 into the pipe 48 in the general directions of the arrows shown in Figure 3. The material so entering the screen, in passing from the screen to the end 42a 0f the nozzle, travels under a vacuum suction created by the stream 50. As soon as the material passes the end 42a, it mingles with the stream and is thereafter 'carried by hydraulic pressure to the right through the pipe 48.

The injector is made of suiicient power, using the principles well understood in the injector art, so that when the screen .44 is introduced in a puddle or pool 52 of water and other material below the general level of the dirt 12, or in any other position below the level of the end of pipe 48, that material carried into the pipe 48 by the injector will be forced clear through the pipe and delivered from its right hand end, notwithstanding tliss elevation of the delivery end of the plpe In the operiation of the device as applied to the particular stone quarry here shown, the mechanism .is first installed in the general position of Figure 1,- thereupon they pump 30 is started, valves 54 and 56 controlling the pipes in which they are located are opened and the water is allowed to travel through pipe 26 to nozzle 22 and through pipe to nozzle 42. The stream of water 24, delivered by nozzle 22, is manually directed to wash down dirt from pile 16 and from layer of dirt 12 into the depression 52 adjacent to the screen 44,-the water, of course, m seeking its lowest level also entermg the pool 52 and covering the `screen 44. the various parts and materials in this positlon, the rapid passage of water through nozzle 42 to form the stream 50 in pipe 48 sucks the water and dirt in pool 52 through the perforations of the screen 44 into the plpe 48 and finally delivers it from the discharge or right hand end of pipe 48. The operator continues to manipulate nozzle 22 until a condition which is illustrated in Figure 2 is reached, in whichl practically all of the free dirt has been removed, leaving the upper surface of the rock 10 clear and clean4k except for more or less large pieces of stone 18 which rest thereon and are afterwards manually removed, if it is found desirable.

Dur glthe operation described, the pipe 48 and t e screen 44 connected with it may be moved if desired to reach the lowest point this pressure ma to which water will flow on top of the rock 10 and this may be done by ordinary workmen without special tools and without the necessity of laying foundations and making other permanent arrangementswhich is ordinarily necessary in installing material for pumping from a lower to a hi her level.

The operator can, by manipuIating the valve 56, control the amount of water delivered to nozzle 42 to thereby provide sufficient power to carry the material to be conveyed through pipe 48, regardless of the height to which it may be necessary to carry the discharge end of the pipe 48 in order to properly dispose of the waste material. In other words, when the discharge end of pipe 48 isl comparatively low as regards the noz,

zle 42, a comparatively low pressure of water may be delivered through nozzle 42 and be increased by opening valve 56 as the ischarge end of pipe 48 is raised. The same result may, of course, be-

accomplished by initially installing different sized nozzles 42. l
